I Application filed August 20, 1917. Serial No. 188,517.

canizing-Patch-Holding Devices, of which the following is a specification.

This invention relates to improvements in vulcanizing patch holding devices and especially to that class of devices designed to hold a self heating patch container which is, adapted to vulcanize tire tubes, water bottles and the like, the fuel for curing the rubber in said patch beingcarried by the said container.

It is an object of this invention to-construct a patch holding device that is in the form of a pair of tongs and having a head with arms projecting therefrom which is provided with gripping means for securely holding the patch container while the sald patch is properly placed upon the article to be repaired.

It is a further object of this invention to provide an instrument used in connection with vulcanizing which is in the form of a pair of pivotally connected members, one of which members is provided with a head adapted to securely hold the patch container,

the holding means comprisin a Spring gripper or magnetic arm secure to said head,

while the other member is ized.

It is also an object of this invention to provide a locln'ng means, which is simple but effective, whereby the tongs may be securely held in closed position after the patch has'been properly placed for 'vulcanizing.

With these and other objects in view, the invention comprises certainnovel constructions, -combinations and arrangements of parts, as will be hereinatfer more fully described and claimed.

In the accompanying drawing forming a part of this specification:

Figure 1 is a side elevation of the patch holding device showing a patch clamped upon an inner tube, certain parts being shown in section.

Fig. 2 is a partial plan view of the patch holding device.

Fig.- 3 is a front elevation ofthe patch holding device partially shown in section rovided with a plate for holding the artic e to be vulcanthe ends of tha arm 18. The grip and the patch container shown in dotted l nes held by the head of said device.

Fig. 4 is a bottom View of the spidered head showing the patch container in dotted lines.

.Fig. 5 is a front elevation of a modified form of the device representing a patch contalner 1n dotted lines as being held in place magnetically.

Fig. 6 is a section taken on line 66 of Fig. 5.

The device forming the subject matter of this inventionis designed for use inconnection with vulcanizingand particularly for holding a vulcanizing patch container while the same may be placed upon an article to be repaired. The formof the device shown is that of a air of tongs 10, which have a pair of hand es 11 and 12 and are pivotally connected at 13. The handles 11 and 12 have extensions 14 and 15, which preferably extend beyond the pivot point 13 and provlde means for extending over the article to be repaired. At the outer end of the extension 14 is a pivotally attached head 16 adapted to have a slight swinging movement about the pivot point 17. At the lower end of the head 16, spider arms 18, 19 and 20 are provided and have a seat portion as 21 adapted to rest upon the container. Formed at the outer end of the extension member 15 is a plate 22, this plate being preferably oblong in form and situated directly under the spider arms, thereby registering therewith when the tongs are closed, so that the article resting upon the said plate will be in the proper position to receive the patch,

which 1s mounted uponthe patch container 24:. The head 16 is provided with a' gripper member 25, which is preferably in the orm of a spring and extends along the upper surface of the arm 18 and has its ends 26 bent downwardl forming grippers, and adapted to extend into grooves 27 formed in per ends 26 securely hold the patch contamerupon the spidered arms and' allow an operator using the tongs to place the said tongs upon the article to be vulcanized without any danger of dropping the said container from the head of the device. The arm '20 is provided with a sto or downwardly extending projection 28 w 'ch centers thepatch container over the said plate.when the tongs are closed.

spring 29 is It will .be necessary to provide means whereby the head will not swing out of position with relation to the said plate, and a rovided which seats against the under sur ace of the extension 14 and the gripper member 25, thereby insuring a perfect alinement of the head member and plate.

The arms 11 and 12 are provided with alock 30 which is pivoted on the arm 12 at 31, and has a head 32 adapted to engage notches 33 secured in the upper edge of the arm 11..

This look provides means whereby the patch will be securely clamped upon the article to be repaired, and obviates any danger of the said patch getting out of place.

The modified form shown in Figs. 5 and 6 has substantially the same head and spidered arm shown in Fig. 1. In this form of the device, there is no spring gripping member to grip the edges of the patch container. The arms 34 and 35 are of such .material, preferably of steel, which will receive a charge of magnetism, thereby forming a magnet of the said arms 34 and 35. The

patch container is made of metal and when placed upon the magnetic arms, is held thereby-and centered over the plate 36 by downwardly projecting stops or detents 37 formed at the ends of the arms 34 and 35.

A spring 38 which holds the head and magnetic arm in proper position with respect to'the plate, rests against the lower edge of the extension 14 and the upper surface of the said arms and allows a proper adjustment of the head member when the patch is clamped upon the article to be reaired.

It will be observed that the device is so constructed that the. patch device may be quickly inserted into the head of the tongs and held thereby, so that the operator of the device may handle the tongs with one hand and adjust the article to be vulcanized with 1. A vulcamzing patch holding devicecomprising a pair of tongs pivoted together and having handle extenslons on one end and clamping extensions on the other end thereof, a patch holding plate on the clamping extension of one of said members, and ahead pivotally supported in registration with said head on the clamping extension of said other member, said head having a pair of transverse arms and a pair of longitudinal arms formed thereon, one'of said arms having a depending extension for engagement with the patch holder, and a spring supported on said head and having its ends extended at opposite points therebelow and for resilient engagement with and for holding said patch holder in position.

2.- A vulcanizing patch holding device comprising a pair of pivoted tongs, one of said tongs having a plate thereon, a head pivotally supported on the other of said tongs opposlte said plate, anelongated spring seated in the center of said head, and having its ends extended below said head for engagement with a patch holder.

3. A vulcanizing patch holding device comprising a pair of ivoted tongs, provided with a stationary p ate, and a resiliently yieldable head, a ri 'd dependingextension on one side of said ead, and'a right angularly disposed spring having extensions below said head between which, and said rigid extension a patch holder is adaptedto be held in operating position.
